An abstract released by the State Intellectual Property Office of China states: "The invention relates to a large-scale offshore wind power access point optimization method based on chance-constrained programming. The method comprises the following steps of: 1) constructing a PCC point optimization selection model which takes the minimum investment cost of new electrical equipment of PCC points meeting different-capacity offshore wind power access and the minimum annual power generation cost of an onshore power grid as an objective function; 2) considering the uncertainty influence of offshore wind power random fluctuations on the operation of a land power grid, and calculating the annual power generation cost of the land power grid by adopting a typical scene method and constructing a random optimal power flow model based on chance-constrained programming; and 3) optimizing the number, the positions and the access power of the PCC points of a large-scale offshore wind power cluster accessed to the given land power grid according to the PCC point optimization selection model, so as to obtain an optimal configuration scheme. Compared with the prior art, the large-scale offshore wind power access point optimization method has the advantages of comprehensive and practical consideration, high solving efficiency, practicability, safety, stability and the like."
